An ankle sprain is an injury to one or more ligaments in the ankle, usually on the outside of the ankle. Ligaments are bands of tissue-like rubber bands– that connect one bone to another and bind the joints together.In the ankle joint,ligaments provide stability by limiting side-to-side movement.However, not all ankle injuries are sprains; they can be fractures of bone, fractures of cartilage or even torn tendons or ligaments.In children, ankle injuries can be growth plate injuries. Ankle injuries often result from a fall,a sudden twist, or a blow that forces the ankle joint out of its normal position. Ankle sprains commonly occur while participating in sports, wearing inappropriate shoes, walking or running on an uneven surface. The signs and symptoms of ankle sprains may include: pain or soreness, swelling, bruising, difficulty walking and stiffness in the joint. All ankle injuries need professional attention, neglecting them can be avoided by prompt diagnosis and treatment.
